B45 Glasses
The B45’s are created from nylon powder in one interlocking Selective Laser Sintering (SLS) print. This negates the need for any fasteners as they are produced assembled.
Through testing a specialised edging technique the clearance between parts has been minimised from the recommended 0.6 to 0.25mm without any fusing occurring. This allows for a tighter relationship using snap-fits between the front frame and each arm.
